WTOP is pointing new Polymarket customers toward a $20 bonus tied to Carlos Narvaez and the Boston Red Sox meeting the Los Angeles Dodgers on Sunday Night Baseball. To get it, a new user has to open an account, make an initial deposit and complete a $10 trade using promo code WTOP.
The offer is aimed only at new users who are at least 18 years old and physically located in an eligible Polymarket state, and it is not available to residents or anyone located in Michigan or Nevada. In practice, the bonus works as platform credit on the site rather than cash in hand: a customer puts in $10 of trading activity, then receives $20 of bonus value that can be used within Polymarket.
That timing matters because the game itself has become a real pull. The Dodgers entered at 69-41 and in first place in the NL West, which is why they were viewed as the consensus favorite, but Boston had a case of its own. The Red Sox came in at 58-51, third in the AL East, after earlier in July they ran off a 15-game winning streak and then carried a three-game heater into the matchup.
Boston also had the kind of road record that can make an underdog look less like a long shot, sitting at 33-22 away from home. That was part of the appeal after the Red Sox beat Los Angeles 9-4 in the series opener, with Ceddane Rafaela delivering the go-ahead two-run homer. The matchup was billed as a 2018 World Series rematch, and it had enough recent form behind it to make the second game more than just another stop on the schedule.
There was still a sharp edge to the setup. Yoshinobu Yamamoto was scheduled to start for Los Angeles and was chasing his 12th win, while Payton Tolle was making his first career start against the Dodgers. So the offer lands at a moment when Boston has momentum, Los Angeles has the stronger record, and eligible users have to decide whether the promotion is worth the entry rules before the game gets going.
For anyone who qualifies, the path is straightforward: register, fund the account, trade $10 and use WTOP. For everyone else, the only thing left is the game itself, and a matchup that has already shown Boston can make the favorite sweat.
